Bun v1.1.39 introduced bun.lock, a JSONC formatted lockfile. bun.lock is human-readable and git-diffable without configuration, at no cost to performance. Learn more.
To teach git how to generate a human-readable diff of Bun’s binary lockfile format (.lockb), add the following to your local or global .gitattributes file:
gitattributes
*.lockb binary diff=lockb
Then add the following to you local git config with:
terminal
git config diff.lockb.textconv bun
git config diff.lockb.binary true
To globally configure git to diff Bun’s lockfile, add the following to your global git config with:
terminal
git config --global diff.lockb.textconv bun
git config --global diff.lockb.binary true

​
How this works

Why this works:
  • textconv tells git to run bun on the file before diffing
  • binary tells git to treat the file as binary (so it doesn’t try to diff it line-by-line)
In Bun, you can execute Bun’s lockfile (bun ./bun.lockb) to generate a human-readable version of the lockfile and git diff can then use that to generate a human-readable diff.
